Designation:D703411Standard Guide forDeriving Acceptable Levels of Airborne ChemicalContaminants in Aircraft Cabins Based on Health andComfort Considerations1This standard is issued under the fixed designation D7034;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide provides methodology to assist in interpret-ing results of air quality measurements conducted in aircraftcabins.In particular,the guide describes methodology forderiving acceptable concentrations for airborne chemicalcontaminants,based on health and comfort considerations.1.2 The procedures for deriving acceptable concentrationsare based on considerations of comfort and health effects,including odor and irritant effects,of individual chemicalcontaminants being evaluated.The guide does not providespecific benchmark or guidance values for individual chemi-cals to compare with results of air quality measurements.1.3 Chemical contaminant exposures under both routine andepisodic conditions for passengers and crew are considered.1.4 This guide does not address airborne microbiologicalcontaminants,which are also important in consideration ofaircraft cabin air quality.This guide also does not addressmethodologies for investigations of air quality complaints.1.5 This guide assumes that a list of chemical contaminantsof potential concern has been developed based on existingconcentration,emission,or material composition data.1.6 The primary information resources for developing ac-ceptable concentrations are databases and documents main-tained or published by cognizant authorities or organizationsconcerned with health effects of exposure to contaminants.1.7 Acceptable concentrations developed through this guidemay be used as a basis for selecting test methods with adequatereliability and sensitivity to assess the acceptability of aircraftcabin environments.1.8 Procedures described in this guide should be carried outin consultation with qualified toxicologists and health effectsspecialists to ensure that acceptable concentrations developedare consistent with the current scientific understanding andknowledge base.1.9 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.10 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory requirements prior to use.2.Referenced Documents2.1 ASTM Standards:2D1356 Terminology Relating to Sampling and Analysis ofAtmospheresD6399 Guide for Selecting Instruments and Methods forMeasuring Air Quality in Aircraft CabinsE609 Terminology Relating to PesticidesE943 Terminology Relating to Biological Effects and Envi-ronmental Fate2.2 Other Standards:314 CFR 25 Airworthiness Standards29 CFR 1910 Occupational Safety And Health Standards40 CFR 50 National Ambient Air Quality Standards3.Terminology3.1 DefinitionsFor definitions of terms used in this guide,refer to Terminologies D1356,E609,and E943.4.Summary of Guide4.1 The purpose of this guide is to provide methodology forinterpretation of air quality data obtained by measurements1This guide is under the jurisdiction of ASTM Committee D22 on AirQualityand is the direct responsibility of Subcommittee D22.05 on Indoor Air.Current edition approved March 1,2011.Published March 2011.Originallyapproved in 2004.Last previous edition approved in 2005 as D7034-05.DOI:10.1520/D7034-11.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from U.S.Government Printing Office Superintendent of Documents,732 N.Capitol St.,NW,Mail Stop:SDE,Washington,DC 20401.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 conducted in aircraft cabins.Acceptable concentrations devel-oped through this guide may also be used as a basis forselecting test methods with adequate reliability and sensitivityfor measuring cabin air quality.4.2 To provide a background for assessment of cabin airquality,the guide summarizes information on the concepts ofexposure,dose,and related health effects,and makes a distinc-tion between chronic(long-term)and acute(short-term)ef-fects.4.3 This guide describes data sources and procedures forderiving acceptable concentrations in aircraft passenger cabins.The acceptable concentrations are based on characterization ofrisk of chronic and acute inhalation exposure.Risk character-ization also includes an assessment of potential o
